When a persona-pinned GPU fine-tune is offline, degrade to the requested quality tier's Bedrock model (Quick->Haiku, Pro->Sonnet) instead of a hardcoded gpt-4o, so Pro genuinely differs from Quick while the pod is off. Legacy/azure engines keep gpt-4o as the floor. Generalize the degraded notice/trace wording (no longer asserts gpt-4o). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
